Rendering basic texture higher, than terrain

hello,

maybe someone here got an idea:

I want to render a map @8k res and export it in 1k res tiles. So every tile is 1025x1025 px. but I need basic-color map/texture and normal map to be 1024x1024 or even better 2048x2048… is there a way, to do this? Or do I havve to calculate the whole terrian twice, 1 time @8097 (for the 1025 heightmaps) and 1 time for 8096 for the 1024 textures?

cheers
